A histogram is better for _____________ data and a frequency polygon is better for ________data.
Ne4ueva [31]

A histogram is better for "discrete" data and a frequency polygon is better for "continuous" data.

<h3>What is histogram?</h3>

A histogram is a data representation that looks like a bar graph and buckets a wide range of categories into columns all along horizontal x-axis.

  • The numeric count or percentage of happenings in the data for every column is represented by the vertical y-axis.
  • Columns can be employed to visualize data distribution patterns.
  • Technical analysts use the MACD histogram in trading to making data in momentum.
  • The MACD histogram columns could provide buy and sell signals earlier than the MACD and signal lines.
<h3>What is frequency polygon?</h3>

Frequency polygons are a graphs depiction of the distribution that aids in data comprehension by utilizing a specific shape.

  • Frequency polygons are comparable to histograms but are more beneficial when comparing two or more different data sets.
  • The graph primarily displays cumulative frequency distribution data as a line graph.
  • Frequency Polygons are a type of graph that deciphers information or data and are broadly used in statistics.
  • This graphic form of data representation aids in the depiction of the data's shape and trend in a systematic and organized manner.
